Do you have a dead light bulb? Are you finding it complicated on choosing the right bulb for your replacement?

With new technology such as LED home use light bulbs and Compact Fluorescent bulbs, Which one shall you choose?

Back in the day when LED was used for small devices, A 100W bulb was brighter than a 40W bulb but this isn’t always the case anymore. Energy saving technology like compact fluorescent and LED mean you can get a light bulb as bright as your old 40W incandescent that uses, for example, just 5 Watts of electricity.

To make sure we get the correct replacement bulb in terms of the brightness (because you don't want to lose any brightness, right?) we need to think in terms of light output.

Light Emitting Diode (LED)

2W - 4W

5W - 7W

8W - 10W

9W - 13W

13W - 18W

Compact Fluorescent

5w

7w

11w

15w

20w

Halogen

18w

28w

42w

53w

70w

Incandescent

25w

40w

60w

75w

100w

Lumens (lm)

230 - 375 lm

400 - 500 lm

700 - 900 lm

900 - 1125 lm

1300 - 1500 lm

If you want to replace your 70W halogen light bulb with a modern LED, the LED will probably use between 13 to 18 Watts of energy.

What is Lumens? / "lm"?

If you imagine one lumen is approximately equal to the amount of light put out by one birthday candle that's one foot away from you, a standard 60-watt bulb puts out around 750-850 lumens of light.

luminous flux, equal to the amount of light emitted per second in a unit solid angle of one steradian from a uniform source of one candela.
